Why Use Exchange 2007 on Windows Server 2008?

As opposed to Windows Server 2003, that is.

Mark Garcia, a Unified Communications and SharePoint product specialist at Microsoft, tackled this question in his blog recently because it's a question he's being asked on a regular basis by customers (which in his case are educational institutions). He came up with six reasons:

• Higher reliability
• Multi-subnet clustering and other clustering enhancements
• Networking improvements
• IIS 7.0 improvements
• Easier deployments
• No upgrading at a later point

You can read the details on each of the reasons, and see screenshots that illustrate them in the original blog post.
